Measuring fuel economy is among our more than 50 tests we conduct on each car we purchase. Our fuel economy numbers are derived from a precision flow meter and are rounded to the nearest mile per gallon (mpg).

CR’s overall mileage is calculated from equal portions of city and highway driving.

Below, we spotlight the top-fuel-efficient cars based on the overall fuel economy test results, omitting electric cars. Complete test results can be found by clicking through to the model pages.
